Bayern Munich coach Hansi Flick hailed "great talent" Jadon Sancho amid links with a move for the Borussia Dortmund star.
"I don't like to talk about players who are under contract to other clubs," he told a news conference.
"I can say that Jadon Sancho has a high quality but in the end he also does Borussia Dortmund very, very well."
Flick added: "He is a great talent and has enormous qualities. That's why you simply have to acknowledge that Dortmund has a very good player there."
Sancho has scored 14 goals and provided 16 assists in 26 Bundesliga games this season.
